Rather use rtrim(). Usage of chop() is not very clear nor consistent for people reading the code after you.

If you are searching for a function that does the same trick as chop in PERL, then you should just do the following code:
<?php
$str
= substr($str, 0, -1);
?>

The question is: why isn't chop() an alias of the code above, rather than something which will trap developpers?
